[9front] panic on hjfs fshalt

[-- Attachment #1: Type: text/plain, Size: 353 bytes --]

Thinkpad x230, behavior began after a sysupdate. I can't say the exact 
date it was updating from, but some time during the "Golden Age of 
Ballooning" period. Now every time I use fshalt I get a panic. The disk 
is an mSATA SSD running hjfs.

Below is my sysinfo, attached is a picture of the error output on 
screen.

It might be relevant as I too got a similar panic today on fshalt on a
tcp booted industrial PC, an Advantech UNO-2271G-E23BE. Pretty sure I
did a sysupdate on 2023-12-18 including kernel. Unfortunately I have
yet to post the sysinfo and on vacation until the 3rd. However I do
have a screenshit with bonus christmas lights.

it very much sounds like the issue that has been
fixed before the last release in the kernel.

the bug is triggered by the following code in fshalt:

	# turn off disk drives
	for(i in $s)
		echo config spec $i switch off >>'#S/sdctl'

i highly suspect you'r *NOT* running the new kernel.
note that mk install is not enougth. you need to
copy it to 9fat for your bootloader to find it
if you boot off a disk.

otherwise, comment it out in fshalt to avoid the crash.

Correct. My complaint is noise. I USB booted and pulled root from the
file server and forgot the kernel on the stick is old. Mistake noted.

You're right that I did forget to do that on this system. However when 
compiling I got an error

Thanks, will do

This happens sometimes when libraries are updated. You'll need to

; mk nuke

them away and replace them. You can do it bit by bit but I usually
just do them all. This is the muscle memory I have for doing these big updates:

cd /sys/src/
mk nuke
mk libs
mk install
mk clean
cd /sys/src/9/pc64
mk install
mk clean
9fs 9fat
cp /amd64/9pc64 /n/9/
unmount /n/9
unmount /n/9fat
rm /srv/dos
fshalt -r

Adjust to taste.

Hope this helps,

thanks, that's what i was forgetting.  still getting used to the
consequences of "programs should do one thing well".  most operating
systems recompile for you, not to say plan 9 should, but to say that
plan 9 expects you to make those decisions yourself.

sorry for the borked attachment btw

make sure you remember to update your kernel in 9fat.
